Manipulation of terahertz radiation using metamaterials

Authors


Abstract

During the past decade electromagnetic metamaterials have realized many exotic phenomena that are difficult or impossible using naturally occurring materials. It is their resonantly enhanced interaction with electromagnetic waves that underpins their attractive qualities, which are increasingly important in the terahertz frequency range. Passive and active terahertz metamaterials and devices have enabled novel functionality and unprecedented terahertz device performance. These demonstrations prove their potential to address the so-called terahertz gap, a technology vacuum associated with the deficiency of natural materials with a desirable terahertz response.
